OK, Genius, fix this one:-)

I suppose this one belongs in the “Retouching” forum, but since they were taken with the D70, and there are so many cleaver people here – I thought it try here first.

I took one Raw picture and converted it two times in PS, first the WB set too match the indoor light, second the outdoor light. As you can see the different is huge between them.

I read an article for some time ago, were they told about the “old days” were the photographer needed too place a plastic filter in front of the windows so the WB would bee the same both inn and outdoor. They followed up telling that this was not needed with digital imaging, since it could bee fixed in the post processing. I have tried that, but failed. Can someone tell me how this can bee done?
